Compare metered searches with distinct website and Docs add-on workflows.
THE ATN TAKE · EDITORIAL ASSESSMENT
Copyscape provides a readable per-search pricing model. Plagiarisma offers a website and a separately scoped Docs add-on, but its premium amount remains unverified. Both require manual review of apparent matches. Plagiarisma’s retrieved terms make confidential-document use unsuitable for endorsement here; Copyscape’s upload-retention questions also remain open. [1][2][7][4][6]
CopyscapeFind matching web text for an existing page or a submitted draft. [1][2]
PlagiarismaWebsite text-match checks, with a separate Google Docs add-on that advertises other writing tools. Accuracy and AI-detection claims have not been tested. [3][4]
Free starting point
CopyscapePublic-URL searches return up to ten results, with additional scan limits. [2]
PlagiarismaWebsite free use is advertised. The separate Docs add-on lists five document scans per day; do not apply that allowance to the website. [3][4]
Paid billing model
CopyscapePremium prepaid searches: 3 cents for the first 200 words, then 1 cent per additional 100 words or part. Confirm currency and minimum purchase before paying. [1][2]
PlagiarismaPaid features are advertised, but amount and currency remain unverified. General terms describe monthly renewal; the FAQ’s three-day premium refund excludes trial orders. [4][5][6]
Supported text workflow
CopyscapePremium accepts pasted text and PDF/Word documents, plus URL batches and the documented API. [1]
PlagiarismaWebsite accepts pasted text, URL or supported documents. The Docs add-on requires installation and account permissions. [3][4]
Usage limits
CopyscapeBatch Search supports up to 10,000 pages per operation; each page and API request is billed as an individual search. [2]
PlagiarismaDocs add-on permissions include managing installed-in documents, connecting to an external service and sending email as the user. Exact website quotas are unresolved. [4][3]
Uploaded material
CopyscapePrivate Index is a product feature, not proof of a complete retention policy. The FAQ’s privacy link returned terms; upload retention and reuse remain unresolved. [2][7]
PlagiarismaTerms characterize submitted content as non-confidential. The privacy policy retains personal data as needed and has deletion exceptions; a precise scan-retention or training policy remains unresolved. [6][8]
Use and result limitations
CopyscapeResults can miss unindexed content and do not certify ownership. Only the documented API permits automated querying. Adult-business permission was not established. [7]
PlagiarismaTerms prohibit obscene/unlawful submissions and require rights to content. This is not an endorsement for confidential uploads or unverified adult-business use. [6]
Affiliate status
CopyscapeNo public commission program was verified in the official pages or the targeted official-site search. No tracking link or application was created. [1][2]
PlagiarismaNo current official cash commission was established. Older indexed FAQ references did not persist in the current retrieved FAQ; no tracking link or enrollment is implied. [5]
Consider it forATN assessment
CopyscapeOccasional permitted text searches where metered use fits better than a recurring allowance. Review matches before drawing conclusions. [1][2][7]
PlagiarismaEvaluating possible overlap in authorized, non-confidential text with manual source review, after checking the exact website or add-on workflow. [3][4][6]
For non-graphic editorial and business text you are authorized to submit. Similarity reports need human review; they do not prove ownership, plagiarism, AI authorship or a successful takedown. No accuracy testing has been performed. A feature listing does not establish adult-business permission.
Plagiarisma’s five daily free scans are stated for its Docs add-on, not established as the website allowance. Copyscape meters Premium searches by words and bills each batch page separately. Estimate the actual workflow before comparing costs. [4][2]
Review access before installing
The Plagiarisma add-on requests document-management, external-service and email-sending permissions. A convenience feature is not a reason to grant access without understanding it. This research used public documentation only and did not install the add-on or upload files. [4]
Do not use a marketing claim as confidentiality evidence
Plagiarisma’s terms characterize submissions as non-confidential, while its privacy policy has retention and deletion exceptions. The policy became accessible through the official add-on link after a direct retrieval failed. That resolves access to the document, not the remaining scan-retention or training questions. [6][8]
